What is Roto Molding?

rotomolding process graphic Rotomolding is a process that produces incredibly durable blackwater RV holding tanks that are tailor-made for the demands of "over the road use." By utilizing this process, we ensure the creation of seamless and watertight tanks. Through the application of high temperatures ranging from 260°C to 370°C, virgin polyethylene resin is melted within a closed mold. The rotational movement uniformly coats the mold's interior, resulting in tank walls with consistent thickness, measuring an impressive 3/8". The exceptional strength of these tanks guarantees superior longevity and durability compared to other plastic RV tanks.
